After adding a DSB, you'll have three serial ports. Each will be fully
usable from all programs that currently use Commodore's serial.device.
Each will be fully usable from the CLI (or from DOS).

The DSB occupies a single slot and passes its connectors out the back
of the same slot it sits in. The driver software has been shown to 
work much more correctly than the Amiga's serial.device (if you 
consider behaving as documented in the RKM as a measure of correctness).

For instance: transmitting an unqueued break in the middle of a currently
executing write will often hang the Amiga's serial.device but works 
perfectly well on our device. (This is the sort of thing I meant by 
working ``better''). Another example: Start and Stop work as documented
in our device but seem not to work at all in serial.device.

From the programmer's point of view having these features work as documented
means an easier time debugging code. From the user's point of view...this
means fewer *if any* unexpected system locks or gurus due to serial activity.

We put in a LOT of effort on the DSB's software. We think you'll be able to
tell. BTW: Shipping starts next week. And includes a thing we're calling
the Serial DisPatcher which will allow any program (which uses serial.device)
to use any expansion serial port with no modifications.
